简单的网络通信，一个客户端，一个服务器端(winsock )

TCP端口扫描，可以获得指定IP段内的主机名，mac地址，存活端口，并将这些信息保存在SQLITE数据库，下次可以直接读取数据库信息，移值性好！(CP port scan, you can get within the segment specified IP host name, mac address, survival ports, and the information stored in the SQLITE database, the next can be read directly, transfer value is good!)

网络活动主机和开放端口扫描源程序，含开发文档，基于C#的rawsocket开发，支持 多线程 支持ARP，ICMP协议的活动主机扫描，支持TCP connect syn fin 三种方式的开放端口扫描，支持udp端口扫描(Networking activities, the host and open source port scan, including the development of the document, based on the C# The rawsocket development, support for multi-threaded support for ARP, ICMP scanning hosting agreement to support the TCP connect syn fin three ways of opening up port scanning, support udp port scan)

用vc6.0实现的强大有界面的sockets通讯程序，可使server端与client端即时通信，需先运行server端。(Vc6.0 achieved using a powerful interface sockets are the communication process, will enable the server-side and client-side real-time communications, the need to run server-side.)

socket 编程基础 里面主要是介绍性文字和少量代码(socket programming which is mainly based introductory text and a small amount of code)

基于网络的视频监控系统 随着时代的发展，人们对安全防范也越来越重视，而数字化视频监控系统在音视频录像、报警录像联动、硬盘存储、多画面显示等方面都有突出表现，因此在安防领域逐渐占有了一席之地。本文提出的基于网络的视频监控系统实现了对数字硬盘录像机的控制功能，其远程客户端软件可以同时播放四路具有高达Dl分辨率的图像数据。 第一章论述了视频监控系统和数据压缩技术的发展动态。 第二章对客户端软件的开发环境及平台进行了选择，并就其中使用的关键技术:windows sockets编程技术、windows多线程技术、windows图像显示技术、MPEG-4编解码与数据传术技术、流媒体技术做了简介。 第三章详细论述了客户端软件的设计及实现。包括客户端软件的整体设计和各模块的设计实现，最后给出了实现结果。 第四章是论述了实时流媒体播放器的设计和实现，包括主要模块设计实现 (网络接收模块、解码模块、显示模块、操作控制模块)、其他模块设计实现(显卡能力探测模块、表面管理模块)、性能优化(缓冲、共享内存、线程模型)。 第五章对系统进行了总结，并为系统进一步发展提出了展望和规划。 (network-based video surveillance system with the development of the times, people are increasingly security attention, and Digital Video Surveillance System in video and audio video, police video linkage, hard disk storage, Multi-screen display, and other aspects outstanding performance in the field gradually Security occupies a place. This paper presents the network-based video surveillance system for the digital disk video recorder to the control function, its remote client software can be broadcast simultaneously Four Dl with high-resolution image data. The first chapter of the video monitoring system and data compression technology developments. Chapter II of the client software development environment and platform choices, and the use of the key technologies : Programming windows sock)

说明：  该源码主要描述了计算机进行数据实时数据传输时所使用的RTP协议，介绍了该协议的基于C++的API函数，及基本的实现过程，有利用实现网络编程。(The main source of data describing the computer real-time data transmission protocol used by RTP, described the agreement based on C++, API functions, and basic implementation process, there is use for network programming.)

关于FTP的代码,支持网络间的文件传输,用户权限的设定.(on FTP code, the support network file transfer, set user privileges.)

IOCP基本原理介绍，主要介绍了如何使用IOCP进行开发。(Introduce the basic principles of IOCP, mainly on how to use IOCP for development.)

远程桌面控制的完整实现源码，设计文件在http://blog.csdn.net/dijkstar/article/details/9076911有详细描述，里面整合了位图压缩、鼠标键盘低级钩子等。里面的每项技术都具有工程参考价值。(Complete implementation of the remote control code, design documents described in detail in http://blog.csdn.net/dijkstar/article/details/9076911, which integrates bitmap compression, low-level mouse and keyboard hooks and so on. Inside each technology with engineering reference value.)
